The buyer of two East Village penthouse apartments connected by a one-of-a-kind, 1,000-pound stainless- steel slide will host a final soiree in his new playground before he has it removed.

The new owner of the two pads atop the East 13th Street building, identified by sources as Daniel Gieschen, a Canadian who made a bundle selling a software company, paid $3.3 million for the ultra-modern residence.

“He plans on inviting all his friends to America for a slide party, and then he wants to donate the slide to a children’s museum or to a charity,” said listing broker Elizabeth Kee of Core.

The curved slide currently provides swift access from the top floor to the living and dining areas, through an 18-foot space that is surrounded by glass railings.

There is also a staircase for people who prefer to walk.

The seller, Phil Galfond, a 27-year-old professional poker player who now splits his time between Vancouver and Las Vegas, spent around $300,000 combining the apartments, building the slide and installing it by crane.

It was a made by Natural Structures, of Oregon, at the behest of Turett Collaborative Architects in New York.

“Think of the slide as one big piece of furniture. It had to be built very specifically. It couldn’t be designed to be so fast that people would fly off it,” manufacturer Wayne Turett told The Post.
